Systems, apparatus, and methods that provide a flexible current sensor capable of measuring current flowing through a conductor without contacting the conductor. In various implementations, a flexible current sensor may have a comparable size, shape, and appearance as a flexible loop of a Rogowski coil, except the current sensor described herein can sense direct current (DC). The current sensors of the present disclosure utilize a novel open loop degaussing mechanism to provide accurate DC current measurements in a conductor. To achieve this, a current sensor includes an AC degaussing coil wrapped around a magnetic core. A driver circuit drives an AC degaussing signal in the AC degaussing core, which operates to reset or degauss the magnetic core, thereby providing more accurate current measurements.
